To better query regional sources of metal(loid) exposure in an under-communicated region, available scientific literature from 50 national universities (undergraduate and graduate theses and dissertations), peer-reviewed journals, and reports published in Spanish and English were synthesized with a focus on metal(loid) bioaccumulation in Peruvian food and medicinal products utilized locally. The study considered 16 metal(loid)s that are known to exert toxic impacts on humans (Hg, Al, Sb, As, Ba, … URL EndNote PDF Read more...

Usman M., Dyer P.S., Brock M., Wade C.M. & Khalid A.N. (2024): Two novel species of arctic-alpine lichen-forming fungi (Ascomycota, Megasporaceae) from the Deosai Plains, Pakistan - MycoKeys, 102: 285–299

Members of the lichen-forming fungal genus Oxneriaria are known to occur in cold polar and high altitudinal environments. Two new species, Oxneriaria crittendenii and O. deosaiensis, are now described from the high altitude Deosai Plains, Pakistan, based on phenotypic, multigene phylogenetic and chemical evidence. Phenotypically, O. crittendenii is characterised by orbicular light-brown thalli 1.5–5 cm across, spot tests (K, C, KC) negative, apothecia pruinose, hymenium initially blue then dark … URL EndNote PDF Read more...

Davydov E.A., Himelbrant D.E., Kuznetsova E.S., Stepanchikova I.S. & Yakovchenko L.S. (2024): Multilocus molecular phylogeny of the Umbilicaria aprina group (Umbilicariaceae, lichenized Ascomycota) supports species level and neo-endemic status of Umbilicaria krascheninnikovii - Plants, 13(5): 729 [23 p.]

The Northeast Asian endemic species of lichen-forming fungus Umbilicaria krascheninnikovii is herein discussed in the global context of biogeography and phylogeny of the U. aprina group. The name U. krascheninnikovii has been erroneously used by lichenologists for Umbilicaria spp. from high latitudes or altitudes worldwide, as there are omphalodisc apothecia and rough “crystals” of a necral layer on the upper surface. To test the monophyly and phylogenetic relationships within the U. aprina group, … URL EndNote PDF Read more...

Budak B., Kalin S.N. & Yapça Ö. (2024): Antiproliferative, antimigratory, and apoptotic effects of diffractaic and vulpinic acids as thioredoxin reductase 1 inhibitors on cervical cancer - Naunyn-Schmiedebergs Archives of Pharmacology, 397(3): 1525-1535

Cervical cancer is among the most frequently observed cancer types in females. New therapeutic targets are needed because of the side impacts of existing cancer drugs and the inadequacy of treatment methods. Thioredoxin reductase 1 (TrxR1) is often overexpressed in many cancer cells, and targeting TrxR1 has become an attractive target for cancer therapy. This study investigated the anticancer impacts of diffractaic and vulpinic acids, lichen secondary metabolites, on the cervical cancer HeLa cell … URL EndNote PDF Read more...

Jung P.T., Briegel-Williams L., Werner L., Jost E., Schultz M., Nuernberg D.J., Grube M. & Lakatos M. (2024): A direct PCR approach with low-biomass insert opens new horizons for molecular sciences on cryptogam communities - Applied and Environmental Microbiology, 2024: 1-16

Molecular sequence data have transformed research on cryptogams (e.g., lichens, microalgae, fungi, and symbionts thereof) but methods are still strongly hampered by the small size and intermingled growth of the target organisms, poor cultivability and detrimental effects of their secondary metabolites. Here, we aim to showcase examples on which a modified direct PCR approach for diverse aspects of molecular work on environmental samples concerning biocrusts, biofilms, and cryptogams gives new options … URL EndNote PDF Read more...

Liu R., Paguirigan J.A., Hur J.S. & Kim W. (2024): Cercosporamide, a polyketide-derived fungal metabolite, serves as an antifungal agent against phytopathogenic fungi - Mycoscience, 65(1): 19-27

An endophytic fungus, Phoma sp. NG-25, produces a set of structurally related polyketides including cercosporamide, phomodione, and usnic acid, among which, cercosporamide has been reported to have strong antifungal and anticancer activities. In this study, Phoma sp. NG-25 was grown in seven growth media to determine the optimal culture condition conducive for cercosporamide production. Cercosporamide production peaked on the eighteenth day of incubation in beef peptone dextrose (BPD) broth media. … URL EndNote PDF Read more...

[in Russian with English abstract: ] Ninety-seven important findings of 66 species of vascular plants, bryophytes, lichens and fungi acquired lately from the Murmansk Region are reported. The findings were defined as important if they were red-listed in Russia and/or Murmansk Region, new for the protected areas, represented other particularly rare species known from not more than five locations in Murmansk Region as well as northernmost localities in Europe or globally.

Gillespie L.J., Sokoloff P.C., Levin G.A., Doubt J. & McMullin R.T. (2024): Vascular plant, bryophyte, and lichen biodiversity of Agguttinni Territorial Park, Baffin Island, Nunavut, Canada: an annotated species checklist of a new Arctic protected area - Check List, 20(2): 279-443

Agguttinni Territorial Park is a large, newly established park on the east-central coast of Baffin Island in Nunavut, Canada. Previous knowledge of the plant and lichen biodiversity was limited and based mostly on collections made during the 1950 Baffin Island Expedition. We conducted a floristic inventory of the park in 2021 and re-examined previous collections. We recorded 141 species of vascular plants belonging to 25 families, 69 species of bryophytes in 27 families, and 93 species of lichens … URL EndNote PDF Read more...

Vagle G.L., Lendemer J.C., Manzitto-Tripp E.A. & McCain C.M. (2024): Patterns and predictors of lichen rarity in a biodiversity hotspot - Biodiversity and Conservation, (2024): 1-22

Understanding the spatial distributions of rarity and diversity is crucial for both targeted conservation efforts and elucidating the mechanisms that underpin species richness patterns. Existing studies suggest local communities with greater species richness also hold higher numbers of low abundance species. Rarity hotspots at the global scale tend to be spatially divergent from species richness hotspots and differ among many taxonomic groups, but much less work has been done to understand rarity … URL EndNote PDF Read more...

Westberg M., Wedin M. & Svensson M. (2024): Myriospora molybdina comb. nov. and the identity of Acarospora hysgina - Nordic Journal of Botany, 2024: e04269

The nomenclature and taxonomy of Acarospora molybdina is revised using morphological and molecular data. The new combination Myriospora molybdina is proposed and Acarospora hysgina is recognized as a distinct species while A. brunneola is reduced to synonymy with A. hysgina. In its new circumscription M. molybdina is an arctic species, in Scandinavia only occurring in northernmost Norway. Further localities are reported from Greenland, Russia, Svalbard and the USA (Alaska). Acarospora hysgina is … URL EndNote PDF Read more...
